GitHub Repo Generator
The GitHub Repository Generator is a free, browser-based tool for building realistic, clearly-fictional GitHub repository card mockups. Set the owner and avatar, repository name, description, topics, primary language and its color dot, plus star and fork counts, then export a crisp PNG in light or dark mode. It's built for developers, technical writers, educators, and content creators who need a believable repo card without cloning a real project.

Frequently asked questions
Is the GitHub repository generator free?
Yes. It's completely free to use with no login, no account, and no watermark on your exported image.
Is it safe and legal to use?
Yes, when used for fictional mockups, demos, education, and design comps. These images are clearly-fictional and not connected to GitHub or any real repository. Never use a mockup to deceive, defraud, or misrepresent a real project's popularity.
Can I use my own avatar and text?
Absolutely. You can upload a custom owner avatar and crop it in the browser, and every field on the card is fully editable to match your brand or project.
Does it export a high-resolution PNG?
Yes. The tool renders at up to 8x pixel ratio and exports a crisp PNG that stays sharp on slides, print, and social media.
Is the export watermark-free?
Yes. Downloaded images have no watermark, so they're ready to drop straight into your docs, README, or deck.
Does it work on mobile?
Yes. The generator runs in any modern mobile or desktop browser, and all processing happens on your device.
